EAS (Ethereum Attestation Service)

New agent-first CLI for EAS! 🔥 Now your agents can make and verify attested data directly from the terminal. npm i -g easctl github.com/ethereum-attes…

These should be onchain attestations on Mainnet. easscan.org/attestation/at…

npm i -g easctl An EAS CLI with built-in schemas, JSON output for agent toolchains, and support for 12+ chains. AI agents are starting to operate onchain. For them to be useful, they need trust — identity, credentials, reputation, accountability. EAS attestations are the primitive for this. Signed, structured, onchain claims that anything in the ecosystem can verify.

with that, the attestation ecosystem must encourage broad experimentation across different chains and communities. it pushes us all forward. it reinforces what developers need. it brings us closer to future we envision. Sign is not the competition. the status quo is.

spicy take from a Binance author evaluating @Sign's attestation service vs EAS. the promise of EAS is to be open, free, tokenless, and permissionless. for any chain. any community. and any builder. binance.com/en/square/post…

happy to support builders making real world impact! 🫶

Excited to see how more real world assets are verifiable using attested data. Congrats to @BitsaveProtocol for making a real impact on local businesses 💙.

The attestation from Bitsave: - gives the real world business an onchain presence, the tokens, and bizmarket as the issuing platform. - describes the instrument they’re issuing (equity, debt, revenue based, or something experimental) - references their submitted docs and disclosures (hashed for privacy) base.easscan.org/attestation/vi…

Builder Highlight! @BitsaveProtocol has tokenized over 60+ real world businesses onchain across Africa. They attest to valid business registrations which enable the tokenized businesses to become a yield bearing asset on @base. Congrats on the progress!!

@jeff_weinstein @stripe Hard to imagine a future where attested data doesn’t play a significant role.

happy friday! @stripe is building entirely new products for (and with) agents, intensely. if you (or your entire startup) would like to join us, please email me.

Your agent can just… attest to things. It’s not hard. It’s EASy.

Already on it 👋 We've been using EAS as the proof-of-delivery layer in our M2M agent escrow on Base: Client locks funds in a settlement contract (24h timeout) AI Architect builds + deploys the requested API Architect signs an EAS attestation (orderId, deliveryUrl, buildHash) Contract reads the UID → releases payment No attestation = no payment. Agents can't fake delivery. We also open-sourced EasyAttest (easyattest.xyz) a few months ago — a no-code interface for creating EAS schemas, submitting attestations, and querying them on Base. Built exactly for this use case: agents proving work to each other without touching Solidity. Now adding an agent skill file so any AI agent can discover and use EasyAttest out of the box. Will share when it's up 🔨

This is increasingly relevant in today's a2a and human: agent environments. If you want a math-based approach to solving reputation where the "reputation score" incentives are balanced, sybil resistant and non-destructive...

Great open-source library for anyone building reputation systems for onchain agents. Transitive Trust for P2P Reputation Systems. 100% open-source.

Agents can now prove agency via @clawproof_ and receive a 24hr @eas_eth delegated attestation they can submit on @base. Smart contracts on Base can verify agents are agents. Still testing, but I think @Dragon_Bot_Z and I wired this up right.

We are seeing increased registrations for the Ethereum Attestation Service on OP Mainnet Would love to see more contracts tagged @eas_eth @brycepatrick @open_labels

Onchain attestations may seem simple on their own, but when linked together they become a powerful way to build reputation across networks 🤝🌐 Here, @mvmurthy of @karmahq_ shares how they use @eas_eth to help projects grow their onchain resumes & track impact over time 🔎🌱
